I had the 5th grade teacher from hell. I could write a book. She was pretty bad for everyone, but for some reason she didnât like me at all. I was probably a âknow it all,â but give me a break. My frontal lobe had not developed yet, so I didnât know how to graciously correct a teacher who pronounced âinfraredâ as âin-FRAYER-d,â or who thought Columbus landed in Florida.
Superior oblique muscle. The superior oblique muscle, or obliquus oculi superior, is a fusiform muscle originating in the upper, medial side of the orbit (i.e. from beside the nose) which abducts, depresses and internally rotates the eye. It is the only extraocular muscle innervated by the trochlear nerve (the fourth cranial nerve).
The lower half contains the remnants of the central canal; the posterior portion of the superior half forms the floor of the body of the fourth ventricle. Cerebellum: The cerebellum is located in the posterior fossa of the skull, dorsal to the pons and medulla. It is separated from the overlying cerebrum by an extension of dura mater, the tentorium cerebelli. It is oval in form, with its widest diameter along the transverse axis.
